5 Claims. (Cl. 30-9-30) This invention relates pliances for cutting hair,

The primary object of this invention is the provision of a hair cutting comb comprising a comb portion and a hair cutting blade so associated therewith as to most efiiciently cut hair under a variety of circumstances.

A further object of this invention is the provision of an improved combination comb and hair cutting blade; the latter being so related to the comb as to permit of the most efiicient disposal of the cut hair. I

A further object of this invention is the provision of an improved arrangement for the application of a cutting blade to a comb.

A further object of this invention is the provision of an improved cutting blade adapted to be associated witha comb.

A further object of this invention is the provi-- sion of improved means for attaching a cutting blade to a comb and positioned to cut the hair and in another position to permit of the stropping of the blade.

Other objects and advantages of the invention will be apparent from the following detailed de scription.

In the accompanying drawing wherein for the purpose of illustration is shown only a preferred embodiment of the invention- Figure 1 is a side elevation, of the comb having the improved blade associated therewith in cutting position.

Figure 2 shows the association of the blade upon the comb to permit the stropping of the blade.

Figures 3 and 4 are enlarged cross sectional views taken substantially n the respective lines shown in Figure 1 of the drawing.

Figure 5 is a side elevation of the preferred construction of the blade.

In the drawing, wherein similar reference characters designate corresponding parts thruout the several views, the letter A may generally designate the combination comb and cutting blade which consists of a comb B and a cutting blade C.

The comb B may be made of hard rubber, plasto improvements in aptic or any other desired material. It includes a solid back portion l0 having teeth ll extending transversely therefrom. The comb in height is tapered from one end to the other, and as shown in the cross sectional view in Figure 4 the teeth ll taper in thickness from the back I 0 towards the scalp engaging ends of the teeth. The teeth may extend from end to end of the comb or be provided in any desired arrangement upon the back of the comb. The back of the comb is provided with a pair of definitely spaced screw threaded openings l3 and I4 therein for the detachable reception of blade attaching screws l6. The blade C is of steel and has a tapered cutting edge 20 thereon. The blade is preferably of uniform thickness from side edge to side edge and from top edge to the cutting edge 20, the latter being beveled to provide a taper at both sides thereof so that notwithstanding which side of the blade is against the comb, the cutting edge will .be slightly spaced from the side surface of the teeth H, as shown in Figure The blade C is provided with semi-circular notches 2! at each side edge thereof closer'to the top edge 22 than the cutting edge and in a definite relation so that whenthe shanks of the screws l6 are received in these notches 2|, the cutting edge of the blade will lie over the teeth of the comb in definitely spaced relation from the free ends of the teeth, as shown in Figure 1 of the drawing. The blade C includes an opening 24 at one end thereof which is adapted to receive a hook or other support, so that a number of the blades can be carried in close proximity to a barber. Otherwise the blade is provided with an area designated at 25 by dotand dash lines in Figure 5 wherein openings are to be made. These openings are definitely located upon the blade so that they will lie over the teeth I I, and not cover the back I0 of the comb, Their function is to permit loose hairs to pass therethru so that the combmay be maintained in a clean condition. This open area 25 may be fully opened or portions thereof may bridge the width of the opening to provide reinforcement for the comb. If desired, the openings may take the form of initials or any other characters desired, as shown in Figures 1 and 2.

In the application of the blade upon the comb it will be noted from Figures 3 and 4 that the blade is maintained by the screws [6 flat against the teeth H and the back of the blade at the tapered or cutting edge 20 slightly spaced from the teeth so as to permit of an efficient shearing,

. noted that theblade; may

This asssures accuracy in cutting and positioning of the blade at all times.

The blade C can be reversed in its position with respect to the back of the comb, so that the cutting margin of the blade is extended beyond the marginal edge of the back of the comb, as shown in Figure 2, to permit stropping of the blade.

In the cutting of hair, if the barber or individual has the blade positionedito wards the scalp with the teeth outermost, the "appliance will cut hair deeper. If the teeth portion of the comb are cut hair quite shallow. The cutting is gradual,

and will not notch the hair.

Due to the efficient arrangement of blade and comb, the device may be used for stripping, as,

a comb including a back and laterally extending teeth, a safety razor type of cutting blade, and means for connecting the blade upon the back of the comb with the cutting edge of the blade facing the teeth of the comb, said means permitting removal of the blade and attachment with its cutting edge extending in an opposite direction beyond the back of the comb for the stropping thereof.

4... In a cutting a"""d.corfrbingi appliance the combination of a combcomprising a back portion and laterally extending spaced teeth, a flat subbetween the scalp and the blade the latter will tanti lly r n ul rh pe tt n bla e h ving a. straight line cutting edge at one longitudinal edge thereof, means for clamping the -liiladeupen the back portion of the comb with the cutting blade extending'laterally over and in well as Wave cutting. For rufling the hair, in A order to produce a wave, the individual performing the operation will lift up the longest locks of hair. From underneath. these-locks the. hair will be notched with the cutting comb in a wave-like fashion. The hair will then be carefully pressed firmly to. the scalp and again the operation will be repeated. It has been found that a repetition of cutting the hair inthis fashion for about four hair cuts will provide a permanent wave which may" be easily maintained. 7

Since the screw threaded openings extend completely thru the back of the comb, it will be be; applied upon either side of the comb.

I Various changes in the shape, size and arrangement of parts may be made to the. form of invention herein shown and, described, without" departing from the spirit of. the invention or the scope. ofthe following claims:

'I claim: I

1. A hair cutting appliance comprising a comb having a back portionand teeth extending therefrom, a: cutting blade; and. means oh the back of the. comb. fordetachably engaging the opposed side margins of the.- blade for-removably holding theblade in operating relation with respect to the,

teeth'of the comb. I

2;; In a cutting-appliance the combination of a comb having a. back portion and teeth, afiat cutting'blade having a' cutting edge and an; opening providing zone thereacross, and means for 'connecting the blade upon the comb with the cutting edge in operating relation with respect to-theteeth of the comb and the opening zone facing the teeth to permit passage of detached hair therethru. J

- 3. In a cutting appliance. thecombinationof engagement'wrth' the teeth and at its cutting edge beihg spaced in a line inwardly'from the outer free ends of said "teeth, said-cutting blade being transversely apertured along the line.- of connection of the teeth with. theback ofthe eomhand extending over a=smallarea along the teeth whereby to permit pasage oi severed hair therethrough.

5. In a hair cutting appliance the combination of a comb including a-selid back portion and laterally extending teeth connected therewith, said back portion having. a pair oi predeterminedly spaced screw threaded openings therein, asube stantially rectangularl-yeshaped cutting blade having recesses inwardly from the opposite edges thereof and opening upon; said: edges, saidscrews being adapted-to fit in said. recesses tohold the blade in cutting relation against. the comb, said bladehaving a cutting edgerandvb'eingof-a size to space the-- cutting edge inwardly from the outer ends of the comb teeth whenthe blade is in. position uponsaid comb, said blade being transversely apertured' therethrough at a zone immediately overlying: the teeth at their-base connection with the back of the comb whereby'to: permit passage of cut hairs therethrough and prevent clogging. 1 Y I GLENN C- MITCHELL.
